Frequently Asked Questions

Is Deco X55 the same as Deco X50?

The Deco X55 and X50 are very similar — both are AX5400 dual-band WiFi 6 systems. The main differences are minor design changes and slight variations in feature sets depending on the region. In terms of performance, they are essentially identical. The X55 is the newer model and the one currently being sold in most markets.

Can I use Deco X55 with my existing TP-Link router?

Yes, you can use Deco X55 in router mode (replacing your existing router) or in access point (AP) mode if you want to keep your current router for some reason. In AP mode, the Deco system extends your existing WiFi network but disables routing features like NAT, firewall, and parental controls. For best results and full features, we recommend router mode.

How many Deco units do I need?

TP-Link recommends 1 unit for up to 2,300 sq ft, 2 units for 4,500 sq ft, and 3 units for 6,500 sq ft. These are estimates — actual coverage depends on wall materials, home layout, and placement. If you're unsure, start with a 2-pack or 3-pack. You can always add more units later, and TP-Link's 30-day return policy gives you time to test in your actual home.

Does HomeShield cost extra?

HomeShield Basic is included free with all Deco X55 systems. It includes network security scans, QoS, basic parental controls (time limits, pause), and weekly reports. HomeShield Pro is $5.99/month and adds DPI-based intrusion prevention, IoT device protection, advanced parental controls with content categories, detailed monthly reports, and priority technical support.

TP-Link Deco X55 is the best budget WiFi 6 mesh system you can buy. At under $250 for a 3-pack, it delivers AX5400 speeds and whole-home coverage at a price that undercuts almost every competitor.

If you want great WiFi 6 without spending a lot, this is the system to get.
